Sex and handedness differences in eye-hand visual reaction times in handball players.

Sex and handedness differences in the eye-dominant hand, the right eye-right hand and the left eye-left hand visual reaction times were studied in 270 right-handed and 56 left -handed young handball players. Reaction time was assessed by a software package. All visual reaction times were longer in women than in men. In the eye-dominant hand and the left eye- left hand visual reaction times, the left-handers had a superiority over the right handers, but there was no difference between the right eye-right hand visual reaction times of the right- and left-handers. In right-handers, all visual reaction times were longer in women than in men, but there was no sex difference in left-handers. The results suggest that left-handed players have probably an intrinsic neurological advantage.
